Summary
Thinning hair often comes down to nutrition — specifically, what your follicles need to keep producing strong, thick strands. This guide explains the biology behind hair growth and why Terry Naturally's Hair Renew Formula® stands out: anchored by millet oil (with the unique compound miliacin), it pairs biotin, B vitamins, zinc, horsetail extract, and key amino acids to support keratin production from the inside out.*
Hair health sits at the intersection of nutrition, stress management^, hormonal balance†
, and genetics—which is why generic advice rarely moves the needle. Most people looking for a hair growth supplement for thinning hair already know the basics: eat well, manage stress^, avoid harsh chemicals. What they're looking for is the nutritional piece that their diet alone isn't providing. Terry Naturally's Hair Renew Formula® addresses this from the inside out with a targeted combination of crucial ingredients—anchored by a botanical most hair supplements don't even include.*

Why hair grows—and Why it sometimes doesn't
Every strand of hair originates in a follicle, a small structure in the scalp that produces and supports hair growth. Follicles go through active growth cycles, and during those cycles, the cells responsible for building hair—called keratinocytes—must produce keratin, the structural protein that gives hair its strength, thickness, and resilience. When keratin production is well-supported by the right nutrients, hair grows in strong and stays that way. When key nutrients are lacking, follicle activity slows, strands become thinner and more fragile, and the visible result is thinning, brittle, or lackluster hair.
The nutrients that matter most for healthy keratin production and follicle function include biotin, specific B vitamins (B2, B5, B6), zinc, and—less commonly known but critically important—millet oil. Hair Renew Formula was built specifically around these building blocks, with each ingredient chosen for its documented role in supporting the biology of healthy hair growth.*
How Hair Renew Formula® supports stronger, thicker hair*
01Millet oil activates keratinocytes
Keratinocytes are the cells that produce keratin — the structural protein that builds hair. Millet oil contains miliacin, a unique compound shown in research to enhance keratinocyte activity, supporting stronger, thicker strands.*
02Biotin supplies the building blocks
Biotin is essential to keratin production and helps maintain the structural integrity of existing strands — making hair less prone to breakage. Hair Renew Formula delivers 5,000 mcg of biotin per dose.*
03B vitamins and Zinc power it all*
Hair follicles are some of the most active cells in the body and need a steady fuel supply. B vitamins (B2, B5, the active P-5-P form of B6, and folic acid) support that cellular energy, while zinc supports protein synthesis and follicle health.*
